HOLDER FOR COLLAPSIIBLE, TUBES Application filed January 18, 1928.Serial No. 247,502.

This invention relates to improvements in supporting stands forcollapsible tubes, and refers more particularly to such devices whereinthe collapsible tubes will be inter- II changeably held in asubstantially upright position.

An important object of the invention in its broader aspects is toprovide such a tube holding device with simplified means for effectingclamping engagement on the tube.

Another object is to provide such a device, wherein the tube isheld bothat its upper and lower ends in such a manner as to be accessible formanual extrusion of the tube contents.

Another object is to provide such a device with a captive service coverfor protecting the contents of the tube when not in use.

With the foregoing and other objects in view, the invention resides inthe novel features of construction, combination and arrangement of partshereinafter set forth, shown by way of illustration in the accompanyingdrawings, and specifically pointed out in the appended claims.

In the drawings, wherein similar reference characters designatecorresponding parts throughout the several views- Figure 1 is a frontelevation of an im proved tube holder embodying the invention,

Fig. 2 is a side elevation thereof,

Fig. 3 is a front elevation with the parts in adjusted position tofacilitate insertion or removal of a tube,

Fig. 4 is a top plan view of the device with the parts in the relativepositions shown in Fig. 1,

Fig. 5 is a vertical transverse sectional view on line 55 of Fig. 2, and

Fig. 6 is a fragmentary vertical sectional view on a larger scale takenon line 6-6 of Fig. 4.

The illustrated embodiment of the invention is in the nature of aportable stand, comprising a pair of spaced leg members 10 and 11 whichare adapted to be disposed longitudinally at opposite. sides of thecollapsible tube 12. Said leg members may conveniently be formed ofsheet metal of considerably less width than the thickness of the tubebody and having outwardly flared portions 13 adjacent their lower endsto provide a suitable sup- I porting base. At their upper ends, said legmembers 10 and 11 are secured to or integral 1 with a head member v13which isannular in form and has a depending peripheral flange 14 adaptedto encircle the upper end of the tube 12. Said head member is furthercharacterized by a frusto-conical lower surface 15, against whichtheupper end wall 16 of the tube is adapted to be seated, and asubstantially central aperture 17 is provided in said head member forthe reception of-the threaded neck 18 of the tube 12, as best shown inFig. 5.

The leg members 10 and 11 are preferably resilient to the extent thatthey may be relatively moved toward and away from each other, and theyare provided with aligned apertures 19 and 20, through which the endportions of the base strip 21 of the tube are adapted to extend, asshown in Figure 1. The apertures 19 and 20 are preferably rectangular inoutline, and of such proportions as to snugly engage the tube base strip21, whereby to'firmly hold the same against lateral displacement withinthe holder. In

order to maintain said leg members in their tube engaging position, aretaining means such as spring clip 22 is pivoted at 23 to the lower-endof the leg member 11 and extends transversely to the other leg member10, with which its curved end 24 is adapted to inter- 1 look.

Suitable means are provided for frictionally'engaging the outer sides ofthe tube 12 and maintaining its upper end wall 16 in the frusto-conicalseat 15. For this purpose, a yoke member 25 is pivoted at 26 at one sideof the head 13; said yoke having curvede'xtremities 27 and 28, which areadapted to be disposed between the outer sides of the tube 12 and theinner side of the peripheral flange 14 and to efiect an interlock withthe tube by pressing the engaged portions of the tube wall inwardly asat 29 in Figure 6. An outwardly and downwardly extending handle 30 ispreferably integral with the yoke 25 to facilitate manipulation of saidyoke, and preferably, a pair of spring clips 31 and 32 are carried bythe flange 14 in such a manner as to retain the curved ends. 27 and 28in the tube clamping position. It will be evident from the drawings,that as the yoke 25 is swung from its unlocking position, shown inFigure 3 to the locking position, shown in Figure 1, that it willpositively force the tube 12 longitudinally to its proper seat withinthe head 13, and this feature in combination with the engagement of thelegs 10 and 11 against the base 21, insures the firm support of thetube.

Preferably, a service cover 33 is associated with the head 13, thatshown in the drawings being pivoted at 34 and having a projection 35which is adapted to be engaged by a de-. tent 36 to hold the same inclosed position. Said service cover 33 overlies the central aperture 17in the head 13 in such a manner as to protect the contents of the tubewhen the same is not in use and doing away with the necessity for thebothersome screw threaded closure caps with which such tubes areprovided by their manufacturers.

In order to position a tube within the novel stand, the parts are firstrelated, as shown in Figure 3, whereupon the tube 12 can be slippedendwise into the holder. Thereafter, the leg members 10 and 11 are movedinwardly toward each other in such a manner as to embrace the tube basestrip 21 and are locked in such a position by the spring 22. The handle30 is then pressed downwardly to cause the curved arms 27 and 28 "toclamp the end portion of the tube body as previously described. Theconstruction of the improved stand is extremely simple, and therefore,adapted for economical production, and furthermore, the device will beextremely attractive in appearance and portable in service.

Obviously, the invention is susceptible of numerous modifications in thedetails of construction and arrangement of parts, and the right isherein reserved to make such changes as fall within the scope of theappended claims.
